RUTHERFORD H. HUNTER, OF WOOSTER, OHIO.

GARBAGE-INCINERATOR.

Application filed October 9, 1915.

a To all whom it may concern:

Be it known that I, RUTHERFORD H. HUNTER, a citizen of the United States, residing at Wooster, in the county; of Wayne and State of Ohlo, have invented a new and useful Garbage-Incinerator,"of which the following is a specification.

My invention relates to incinerators for the consumption of garbage and other combustible refuse. Its object is to provide a simple andetticient means for the consumption of garbage which accumulates in and about residences and kitchens, hospitals and other public places, in such a manner as to avoid emission of odors,.and be in all respects clean and sanitary.

It consists mainly of a stovelike furnace for gas heating, constructed to maintain a high degree of heat without outward radiation thereof, and provided with a fire-pot or bowl suspended above the gas burner to receive garbage deposited therein through the stove lid, and means for elevating the bowl automatically when lightened by the evaporation of the moisture and the partial consumption of the mass of garbage, so as to shut off the flow of gas to the burner, and at the same time close the draft on the outside of the bowl and direct it through the remnants of the garbage until the whole mass is consumed by the fire generated therein before the shutting off of the gas.

It further consists of improved means for so controlling the draft within the stove body as to prevent the escape of odors therefrom, except through stove. pipe and chimney, all as hereinafter fully set forth and as stated in the appended claims.

My invention is illustrated by the accompanying drawings in which similar letters and figures of reference indicate like parts.

Referring thereto, Figure 1 1s a View of a garbage incinerator embodying my inven- Specification of Letters Patent.

mechanism, shown in Fig. 1 on dotted line VlV, and Fig. 7 is an enlarged detail View of part of my device for rotating the quick closing gas .valve, on the dotted line ST of Fig. 1.

Referring now to details of the drawing, A is the outer metal casing of the incinerator; Bis a metallicbowl for the reception of garbage through the circular lid 2; C is a circular gas burner; D is a door for the incinerator, and E is a quick closing valve for automatically cutting ofi the flow of gas to the burner C, as hereafter set forth.

The outer casing 1 incloses a cylindricalheat insulator, constructed preferably of folds of asbestos with air circulating channels 11 through the folds 10, (Fig. 2); external air is admitted thereto by the apertures 14, and the air circulation is shown by the arrows a a. A heat resisting lining, in two sections, 3 and 4, is mounted within and adjacent said heat insulator; the upper section, 3 has a ledge 3 adapted to over hang the circular rim 12 of the fire bowl B in such a manner as to shut off the air draft shown by the arrows a when raised against said ledge, and to open said air fine when lowered, as shown by the dotted line 12' in Fig. 1. The upper edge of the lower section 4 is chamfered off as at 4 for this purpose. The bowl B is pivotally suspended by means of the opposite studs 31 in a circular hanger 30, which' is supported at one side, 28, by a projection 29 secured to the wall 4, and at the opposite side by an arm 32 which is actuated vertically through a slot in the walls of the incinerator body, as shown in Fig. 1, and by means of the valve controlling apparatus shown in section in Fig. 3. The latter comprises a wheel and axle 18, 17, mounted in ball bearings, substantially as shown in Fig. 3; the wheel is adapted to be actuated in one direction by the hand lever 19, and in the opposite direction by means of the weight and cord 0 2, but a spiral spring or other actuating means may be substituted therefor, if preferred; the object of said latter movement is to elevate the fire bowl B by means of the lift-rod 21 when the weight of said bowl and contents become less than the actuating force on said wheel, and thus automatically closes the air channel between the rim 12 of said bowl and said ledge 3, as aforesaid. To facilitate this object, and at the same time to shut off a the flow of gas to the burner C through the pipe 23, I construct a quick acting gas valveplug 21, mounted in a suitable support 16, and close the same by a fractional revolution of said wheel 20, as hereafter stated. Said valve is located'in the gas conducting pipe held in position by the support 16, (Fig. 3,) and is held in proper tension by the spiral spring the latter is mounted in the cavity36 of the sleeve 41 which fits loosely in a depression 4-2 formed in the adjacent side of said wheel, and permits a limited endwise movement of said valve-plug with pressure thereon suflicient to prevent the flow of gas when the plug is slightly turned by the action of said wheel. A lift rod 21 is attached on the opposite side of said wheel near its periphery by a pitman connection with ball bearings, and is curved as shown in Fig. el so as to permit said pitman connection to reach the dead point 20 at a quarter revolution of the wheel with accelerated force sufficient to rotate said plug. The interlocking lugs 34, 38 and 39, (Figs. 6 and 7) on said wheel 18 and valve plug head (Fig. 7), respectively, engage each other by the rotation of said wheel and thus serve to quickly close said valve simultaneously with the lifting of said bowl B and the closing of the air passage a as aforesaid. The pipe connection which leads to said valve is not shown in the drawings because unnecessary and easily understood.

The operation is as follows: The gas Valve E is opened when the bowl B is filled with garbage, by turning the hand lever 19, which thereby lowers the bowl to a point shown by the dotted line 12', Fig. 1, and opens the said air passages a and gas is admitted to the burner C through the mixing valve 26, 27 in the usual well known way. The flames from the burner attack the garbage within the bowl directly through a grating in its bottom, and envelop the same with 'an intense heat which consumes rapidly the con tents until they are so lightened as to permit the action of said wheel to overbalance the weight of the bowl and contents, whereupon the latter rises automatically and the gas valve E is closed, and the said air channels a are also substantially closed, a slight draft only being admitted therethrough to carry off any fumes that way arise, the apertures therefor being shown by the dotted lines at the arrows at said channels. when said channels are thus closed consumption of the garbage has progressed to a charred and kindled condition which continues to burn by the direct draft of air therethrough until the whole mass is consumed, the ashes therefrom falling down into the ash pan at the bottom, and the incinerator is ready for a new charge.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent is 1. In a device of the character described, the combination with a stove having an asbestos lining adapted to act also as an air passage within the outer walls, a heat resisting lining adjacent said asbestos lining, formed in two parts, the lower part of said lining having a slot at one side, and terminating against the upper part, the upper part terminating at its bottom with a ledge overhanging said lower part, a metallic bowl for garbage consumption pivotally suspended between the walls of said lower part, and having a rim at its top adapted to engage said ledge, a support for said bowl hinged at one side to said lower lining, and having an arm projected through said slot in the opposite side of said lining, a valve controlling mechanism comprising a valve and gas pipe connection, a quick acting valve plug for said valve, its outer end having a pair of studs opposite each other, a wheel mounted on an axle opposite said valve-plug, and having a lug adapted to engage said valveplug studs when rotated, a pitman rod pivoted on said wheel in operative engagement with the outer end of said projected arm,

means for manually rotating said wheel, means for exerting force upon said wheel in a direction to close said valve by its rotation when the weight of said bowl and contents become less than the force exerted on said wheel, and said bowl is lifted thereby with its rim against said ledge, and a gas burner under said bowl having gas connections with said valve, substantially as set forth.

2. In a device of the character described, the combination with a stove, a metallic bowl suspended therein having a grated bottom, heat resisting lining about and above said bowl having a projecting ledge inwardly, a rim on said bowl to meet-said ledge when said bowl is elevated, the bowl and its rim spaced from the lining to form a draft space up around the outside of the bowl, and means, including a power propelled wheel, for lifting the rim of said bowl against said ledge when said bowl and contents have been lightened by the partial combustion of the latter, and simultaneously thereby changing the air drafts within said stove, substantially as set forth.

3. In a device of the character described, the combination with a gas stove, a metallic bowl movably suspended therein, a lining in said stove about said bowl having an inwardly projecting ledge, a rim around the top of said bowl to engage said ledge when the bowl is elevated, said bowl and its rim spaced from the lining to form a draft space up around the outside of the bowl, said draft space limited by the engagement of said ledge, means for automatically elevating said bowl While garbage therein is being consumed and thereby lightened, and means for automatically shutting ofi the flow of the gas to said stove after partial consumption of the garbage therein, substantially as set fOI'th. 10

In Witness whereof I hereunto set my hand this 25 day of August, A. D. 1915.
